Formula for Percentile Rank

Grouped Data

The formula to find the percentile rank for a given score in grouped data is:

PR = [ ( (X - L) / i ) * f + CF ] / N * 100

Where:
PR = Percentile Rank
X = The score value
L = Lower boundary of the score's class
i = Class interval size
f = Frequency of the score's class
CF = Cumulative frequency of the class before the score's class
N = Total number of data values

Ungrouped Data

The formula to find the percentile rank for a given score in ungrouped data is:

PR = ( (Number of values below X + 0.5 × number of values equal to X) ÷ Total number of values ) × 100
